| Abstract: | To achieve the simulation for IR detection of spatial targets, analysis and analogy calculation of the temperature field of the target in spa is needed. One of the most important boundary condition is the surface material natural parameters of targets. Bidirectional reflectance distribution function(BRDF) method to measure target surface reflectance is studied and the BRDF measuring spectrum and laser reflectance feature platform is built. Thermal parameters of some typical thermal control coating on spatial targets are measured. The measuring tests indicate that the reflectance of white paint coating SR107 is 0.785 while the input angle is 0°. The tests also show that the reflectances of OSR，F46 and polyimide thin film are greater than 90%． |
